ALBERT A. MARLOW, OF BOUNDBROOK, NEW JERSEY.

COOLING AND GONDENSING TOWER.

T 0 all whom it may concern:

Be it known that I, ALBERT A. MARLow, a citizen of the United States, residing at Boundbrook, in the county of Somerset and State of New Jersey, have invented certain new and useful Improvements in Cooling or Condensing Towers, of which the following is a specification.

The invention relates to towers for cooling or condensing fumes or gases in the manufacture of sulfuric acid.

The objects of the invention are to provide a cooling tower in which a saving of acid will be effected by reason of a quicker and better condensing of the fumes; to protect the chambers from overheating; to effect a better mixture of the fumes and hence purer acid; to effect a saving of space; to effect a saving of the water used in cooling and to prevent its splashing over the plant and finally to provide a tower in which the parts are accessible from the outside of the framework for repairs, &c. These objects I accomplish by the construction shown in the accompanying drawings in which:

Figure 1 is a side elevation of my improved cooling or condensing tower. Fig. 2 is a sectional end elevation thereof. Fig. 3 is a fragmentary top plan view. Fig. 4 is a horizontal sectional view on line 4-4, of Fig. 1. Fig. 5 is an enlarged vertical section on line 55 Fig. 4, and Fig. 6 is a sectional side elevation of the acid outlet receptacle.

The framework of the tower comprises a series of uprights A connected by a series of longitudinal bars I), secured at an incline in recesses in the inner sides of the uprights so that the upper edges of the bars I) will project beyond the inner faces of the uprights A and form supporting ledges. Transverse cross pieces (Z connect the end uprights A in the planes of certain of the side bars I). The upper ends of the uprights A, are connected by longitudinal top plates g, on which rest upper plates 6, which support the transverse cross pieces 0, c.

T, T, T are three fume chambers resting one above the other on floors 2, 2, 2, supported on the bars I) and cross pieces (1. These chambers are formed of lead and are connected by two series of lead tubes or flues U; the lower series of tubes connecting the top of the lower fume chamber T with the bottom of the middle chamber T and the upper series of flues connecting the top of the middle chamber with the bottom of the top chamber T. The

Specification of Letters Patent.

Serial No. 402,822.

bottom chamber T is provided with one or more inlets 7;, for the fumes or gases and the upper chamber T is provided with an outlet 0, therefor. The top of the upper chamber T is formed or provided with an open-top waterpan or receptacle t, the side flanges of which are secured under the plates 6, e, and the end flanges of which rest on the upper end cross pieces (Z, (Z. Cleats p, p, of lead connect the pan t with the cross pieces c and. also serve as baffles to retard the flow of water from the supply pipef at one end of the pan to the outlet pipe lr, at the opposite end. This outlet pipe it" discharges into the funnel-like mouth of a down take pipe 75 which discharges into one end of a middle pan t on top of the middle fume chamber T, while a like down take pipe 7r, conducts the water to one end of the lower pan 15 on top of the bottom chamber T and the outlet k at the opposite end thereof leads to waste. The pans t, t are provided with baffle plates which form a serpentine or zig-zag passage from the inlet to the outlet ends thereof.

The outlets of the pans t, t, t are provided with removable tubular plugs 7: so as to retain the water at a suitable height in the pans, and permit of washing out any sediment.

The bottom fume chamber T is provided with an acid outlet T, trapped or sealed atits lower end in the usual receptacle X which discharges into an ofl'take pipe w. The fumes entering the lower chamber T through pipes i, will pass upward through flues U, into the middle chamber, thence through the flues to the top chamber where further condensation takes place and from which they pass by the pipe C for further treatment or to waste, as may be desired. The tubes U and the fume chambers are both water and air cooled which renders them very effective in condensing the fumes, and the open framework renders all of the parts accessible for repairs &c.

The number of chambers and series of fines in a tower may increase, and any number of towers so constructed may be employed. In cold weather the circulation of cold air around the chambers and flues may be relied on without the water circulation, if desired.

What I claim is:

1. A cooling or condensing tower comprising a plurality of superposed closed chambers, having exposed flues connectng the upper side of one chamber withthe lower side of the next chamber, water pans on the up per sides of the chambers; the lower ends of the fines extending through the adjacent pan or pans but not communicating therewith, and means for effecting a flow of water through the pans.

- ,2. A cooling or condensing tower comprising an open framework, superposed closed condensing or cooling chambers mounted therein, series of Vertical exposed fluescon necting the adjacent sides of the chambers, open top water pans on the upper sides of the chambers but having, no communication therewith, and means forefi'ecting a flow of water through the pans and from one pan to the other.

' 1 3. A-coolmg or condensing tower comprising, an open framework, superposed. chambers supported therein, vertical series of fines connecting the adjacent sides of the chambers, the lower chamber having an inlet and the upper chamber an outlet, water pans on the top of the chambers, baflies in the pans to form a zig-zag course for the water, and means for effecting a flow of water through the pans and around the lower ends of said pipes.

4. A cooling or condensing tower comprising, an open work frame including uprights, longitudinal bars, floors supported on said bars, chambers supported on said floors, vertical flues connecting the adjacent sides of the chambers, water pans on top of the chambers, a connection between the outlet end of one pan and the inlet end of the pan therebelow, baffle plates in the lower pans, cross pieces over the upper pan and baffie forming cleats connecting the cross pieces with the bottom of the upper pan.

In testimony whereof I affix my signature, in presence of two witnesses.
